In the wake of a record 37 confirmed cases of tetanus this year, doctors across the United States warn that the disease could surge as vaccination rates wane amid escalating climate‑driven disasters.
Background/Context
Tetanus, a bacterial infection that clutches the nervous system and causes life‑threatening muscle spasms, has been largely contained in the U.S. since the mid‑1900s thanks to the diphtheria‑tetanus‑pertussis (DTaP) vaccine. But CDC data released last week shows a steady tetanus vaccine decline in kindergarten through high school students across 67 states, with the sharpest drop in Florida, Texas, and Kansas—states that account for roughly 30% of the country’s most intense hurricanes, tornadoes, and flood events.
Climate scientists estimate that hurricanes of Category 5 strength, which historically have damaged the infrastructure of the U.S. Gulf Coast, will increase in frequency by 15‑20% over the next decade. With fewer children receiving the booster shots that are required every 10 years for adults, the risk of outbreaks after a disaster may rise dramatically.
Because tetanus is contracted via wounds contaminated by the soil bacterium Clostridium tetani, an increase in exposed skin injuries from broken roads, fallen trees, and collapsed buildings could translate into a higher incidence of the disease—particularly among populations that may not have received the full DTaP series.
Key Developments
- Case Numbers Rise. The CDC’s latest report notes 32 cases in 2024 and 37 confirmed cases this year, the highest in a decade. Most infections occurred in children under 12, with 12 of the 37 cases in kindergarteners.
- Vaccination Decline. Nationwide DTaP coverage fell from 94.1% in the 2016‑17 school year to 88.8% in 2024‑25. In Florida, coverage dropped from 92% to 86%, while Texas saw a 5% drop over the same period. These reductions are most pronounced in low‑income communities reliant on school‑based health initiatives.
- Disaster Correlation. Florida’s Gulf Coast experienced 13 Category 4 and 3 Category 5 hurricanes last season, and Texas had 7 tornado outbreaks over 12 weeks. In both states, local health departments reported spike in puncture wounds requiring emergency treatment—yet the number of tetanus shots administered fell by 12% after each disaster.
- Economic Impact. The average cost of a full ICU stay for a tetanus patient, including antibiotics, immune globulin, and mechanical ventilation, exceeds $250,000. In 2019, an unvaccinated six‑year‑old boy in Oregon incurred nearly $1 million in medical bills after a camping trip injury. The cost burden has prompted some school districts to reevaluate vaccination mandates.
Impact Analysis
For international students and their families, the implications are clear. Many come from countries where tetanus vaccination is not mandatory, and they may not be aware of U.S. booster schedules. A 2025 survey of international medical students found that only 43% knew they needed a tetanus shot every 10 years after leaving school, with 27% saying their parents had no record of vaccinating them as children. In the event of a natural disaster—common on U.S. college campuses—these students could face increased risk of exposure.
For parents, the message is urgent. “You might think tetanus is a thing of the past,” says Dr. Mobeen Rathore, chief of pediatric infectious diseases at the University of Florida. “But when you combine a lower vaccination rate with the fact that a broken window or a fallen tree can give you an inoculating wound, the risk goes up dramatically.”
Public health officials in the Department of Health and Human Services have issued a new bulletin urging schools to reinstate school‑based vaccination programs, especially in high‑risk climate zones. Trump, in his capacity as current President, has pledged $250 million in federal grants to bolster school health services with an emphasis on boosting vaccine coverage.
Expert Insights/Tips
Know Your Schedule. The DTaP series includes five shots: at 2, 4, 6, 15‑18 months, and 4‑6 years. A booster is recommended every 10 years thereafter. Many adults forget they need it, especially if they last received it as a child.
Get the Tdap at 11‑12 years. The Tdap shot, which adds a pertussis booster, covers tetanus for teens and is required for school enrollment in most states.
Seek Immediate Care After Injuries. If you sustain a puncture wound—whether at home, outdoors, or during a construction project—seek prompt medical attention. Even if you have had the full series, re‑vaccination may be necessary after 10 years.
Use Online Tools. Many state health departments now offer vaccine trackers. For example, Florida’s HealthLink platform allows parents to log their child’s vaccination records and receive reminders.
Advocate for Policy Change. If you see your school’s vaccination requirements loosening, contact local representatives and push for renewed mandates. The CDC’s current position is that “a well‑margined program that includes boosters for all ages is essential to prevent resurgence.”
Looking Ahead
Projections from the American Society of Tropical Medicine suggest that, without significant public health intervention, tetanus cases could rise by 25% in the next five years in the U.S. This forecast is based on a 7% annual increase in extreme weather events and a 3% annual decline in DTaP coverage in coastal states.
President Trump has announced a “National Vaccine Protection Initiative” at the next federal health summit, promising to allocate resources not only for childhood immunizations but also for adult booster programs. However, critics argue that the initiative lacks enforcement mechanisms—particularly in states where school districts have autonomously decided to omit mandatory tetanus boosters from their health curricula.
Researchers at Stanford University’s Climate Health Program indicate that a multi‑pronged strategy—combining school‑based vaccination, community outreach, and rapid post‑disaster wound care—will be the most effective approach to curb tetanus risk. They are calling for a public‑health pilot in three high‑risk states to evaluate this model.
In a country where the U.S. current President has emphasized public health and safety in his administration’s agenda, the resurgence of tetanus serves as a stark reminder that vaccination is still the first line of defense against preventable diseases—especially as the climate crisis opens doors for more frequent and severe disasters.
